Application filed November 1 1, 1927. Serial No. 232,625. l

My invention i'elates'to new and useful improvements in ventilating sashes, and the same is adaptedin association with the conventional rain shield employed in connection with the window frame at the interior of a building. c i The purpose of my novel ventilating sash tiltable and removable Window sash. frame may be released from its position as a part of the window to be supported connecting wall of a. conventional window rain shield. 4

The main object of the invention is i0 pl'O vide a ventilating sash, the'sash portion of which is normally tiltable, and which may be radnall released from its normal )ositio'n a: Y

to a tilted position against the connecting wall of a conventional window rain shield.

Another object resides in; intentionally maintaining the sash whereby the same will be prevented from being jarred or otherwise disturbed, probably resulting in the breakage of the panes v thereof. 1

A further object resides in providing a construction in association with the rain shield, whereby the sash may be supported in an elevated position to further protect the interior of the building from the entrance of rain, while at the same time allowing for the proper ventilating of the room.

Another object residesin providing tensional means whereby the elevated sash will displacement. Other various novel objects andadvantages of my improved ventilating sash will become apparent as the same is better understood from follow.

Now for a more detailed invention I refer to the like ni'imerals'designate like parts.

For convenience in properly illustrating manner in whichmy improvedventilatdescription of my drawing in WlllCll' ing sash-is mounted, I represent in the clrawingthe sill A or" the usual construction. The conventional Window rain ing'wall C.

In carrying out my invention, I provide a preferably having its ends j amb board 1,

shield includes side walls B, and the connect"- window frame I connected to 'the respective vertical frame of the conventional window" frame. The

same is adapted to be. positioned in a horizontal plane, and" substantially coplanar with the top edge of thecon-necting wall C.

The jainb board is provided with the ja inb which the upper edge po'rf" is adapted to bear. The

A stop strip" '5 is secured to ea'cli side wall of the rain shield, softhat the one longitu'di ml edge thereof will bear against the connectingwall 0 thereof, in-a manner clearly shown in Figured. The strip is preferably tapered throughout its length, and is en larged 'at 6 to provide abase portion against the inclined'outeredge of which the sash Atthe upper .end shoulder 7 is provided, at'the outer end" of which upstanding lug-8' is formed.

of this base portion a the sash is to *be superally referred to'by the numeral 9, each of Y which is adapted to respective side walls of the rain-shield; In; supporting the respective'tensional devices; I provide a bracket 10, having'a-pair (if-de the :sameis secured to the top edge oft-he at each end of one longitudinal edge of the be supported uponihe These" lug members :are formed i intermediate portion" thereof'is formed with an upstanding flange- 'which flanges are project a substantial tive vupstanding outer sideof the respective flanges 12 and 13. The coiled spring 17 is convoluted about the bushing and disposed between the respecflanges of the brackets, in a manner whereby one end portion thereof is secured within the opening-in the upstanding flange 12 at 18. The opposite end of the spring is fixed tothe bushing.

An elongated arm 19 is formed with an opening adjacent one end thereof, through which abolt 20 extends. This bolt 20 projects through'the bushing and for a substantial distance beyond the opposite end f thereof. Suitablewashers 21-21 are interof the arm against I so posed between the head of the bolt and one side of the arm, and between the opposite side the end of the bushing. The projecting end keyed thereon the pulley wheel 22, while the nut 23 threaded on the threaded end of the bolt is adapted to tightlyengage the wheel against the end of the bushing. Suitable washers may be interposed between the-nut.

An extension 25 0f substantially U-shape cross section .is'formed with an elongated longitudinally extending slot 26, through for securing said exinner end portion of the extension is adapted to engage the under side of the arm whereby the extension will be maintained rigidly with i the arm when the same is in engaged position 00 with the jamb board, as is shown in Figure 1. The outer end of the extension is bifurcated between the furcations of which the roller 27 is rotatably mounted. This roller is adapted to engagefthe inner upper portion of the. sash when the same is in its normal upright position.

It will be seen that when it is desired to a release the sash 3 to provide ventilation for the room,

the flexible strand 24: is pulled, whereby the pulley wheel 22 will cause the rotation of the bushing 16, and theconse fquent lowering of the arm 19.. This action is against the tensionof the spring 17, and in this mannerthe sash may be gradually lowered to the dotted line position as shown distance beyond therepresented in andv , side thereof.

'When the roller 27 has-passed over the top edge thereof, the strand 24 may thence be released, which will allow the extension 25 to bear tensionally against the top edge of the sash. In this position, the sash is prevented from becomingdisplaced due to this tension engagement of the extension.

\Vhen it is desired to elevate the sash in order to prevent any entrance of rain within the room, the sash is lifted to the position construction. The bottom of the sash is 81; a the drawings by dotted line then suppored upon the respective shoulders 7 of the base portion 6 and continue to engage It will be seen that I have provided a very sash, which may be tilted, from its normal positioncto allow for the Howmay beelevated to a higher position, whereby rain will be entirely. prevented from entering the room. In each instance the tensional device I have provided will engage the roller 27 will the sash at the now outer on I the sash so as to prevent any liability that the same will become displaced and damaged. e

Having thus described the invention, what I claim as new and desire to secure by ters Patent is V I 1.
